 - [ ] После `docker restart` anti-torrent правила продолжают восстанавливаться корректно и не ломаются host firewall логикой.
 - [ ] Проверено, где реально проходит VPN-трафик в вашей Docker-схеме (`INPUT` vs `FORWARD`) и это отражено в эксплуатационной заметке.
 - [ ] Для release-кандидата зафиксирован итог проверки `INPUT` vs `FORWARD` на реальном сервере (команды/логи/вывод) и подтверждено, что текущие правила firewall покрывают реальный путь трафика.
+- [ ] `status` показывает блок `Docker/Amnezia port path` с полями `docker_userland_proxy`, `published_udp_port` и note про Docker-managed `FORWARD`.
+- [ ] Если `docker_userland_proxy=false` и `FORWARD policy DROP`, при отсутствии явных Docker accept-признаков `status` выводит warning, но `awg2-harness` не изменяет `FORWARD` автоматически.
+- [ ] Сверено соответствие: `config host_firewall.amnezia_port` ↔ опубликованный Docker UDP host port ↔ `docker exec amnezia-awg2 wg show` (`listening port`).

 `host_firewall.ssh_port` — SSH порт хоста, который обязательно должен быть открыт. Production default: `2323`.
 
-`host_firewall.amnezia_port` — порт Amnezia на хосте. Production default: `443`.
+`host_firewall.amnezia_port` — внешний UDP/TCP порт Amnezia, который AWG2 открывает в host `INPUT` (в зависимости от `host_firewall.amnezia_protocols`). Значение должно совпадать с портом, указанным в панели/инсталляторе AmneziaWG. В старых инсталляциях это мог быть `44344`, в новой целевой конфигурации default — `443`.
 
 `host_firewall.amnezia_protocols` — протоколы для порта Amnezia (`udp`, `tcp` или оба).
 
+Важно: `awg2-harness` не управляет host `FORWARD`/Docker NAT-цепочками. Проект сознательно не добавляет универсальные правила в `FORWARD` и не меняет Docker-managed forwarding path.
+
 `host_firewall.allow_icmp` — разрешать ICMP/ICMPv6 на входе.
 
 `host_firewall.default_input_policy` — политика INPUT chain (`drop` или `accept`). Для production рекомендуется `drop`.
